Tutorial on setting up a CAPA, CAPRKE2, and other supported providers

[valaparthvi]

As someone new to CAPI, I find the document is missing end-to-end tutorials for supported providers other than docker. While there is information on setting up Infrastructure Providers such as CAPA and CAPZ, it does not say next instructions as https://docs.rancher-turtles.com/docs/next/category/your-first-cluster does.

It would be helpful to have quickstart guides for other providers as well.

• Document CAPA + RKE2 cluster and provider installation #117
• Document basic CAPA EKS cluster installation #115
• Document CAPD + RKE2 cluster and provider installation #116
